Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718636, here are decompositions:

97 + 8718539 = 8718636
149 + 8718487 = 8718636
167 + 8718469 = 8718636
197 + 8718439 = 8718636
229 + 8718407 = 8718636
293 + 8718343 = 8718636
359 + 8718277 = 8718636
389 + 8718247 = 8718636

Showing the first eight; more decompositions exist.
